From 969affd276dec81a35a5ad10d4e05e62e93b380b Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 7 Feb 2008 11:58:54 -0500 Subject: sysfs: remove BUG_ON() from sysfs_remove_group() It's possible that the caller of sysfs_remove_group messed up and passed in an attribute group that was not really registered to this kobject. But don't panic for such a foolish error, spit out a warning about what happened, and continue on our way safely.
